Q

Free communication effect is in direct proportion to __________.

🔍 Key Concepts

• Free surface (free communication) effect and how it reduces stability • How flooded compartment dimensions influence the movement of water • Relationship between moment of inertia of a fluid surface and tank/space dimensions

💭 Think About

• Think about which dimension(s) let water move side-to-side when the ship heels: does length, width, or both matter for how much water can shift? • Visualize a compartment flooding and the ship rolling: in which direction is the water actually sloshing, and what measurement of the space controls how far its center of gravity can travel? • Consider whether increasing only one dimension (length or width) always increases the heeling effect, or if the effect depends mainly on one of them.

✅ Before You Answer

• Identify which dimension is perpendicular to the axis of roll, since that controls free surface effect • Recall that the greater the distance the water’s center of gravity can shift, the greater the free communication effect • Make sure you are thinking about breadth across the ship vs. fore‑and‑aft length, and how the ship actually rolls in the water
